A method for inhibiting the deposition of organic contaminants in a pulp and papermaking system comprising adding to the system an effective amount for the purpose of a detackifying composition comprising an anionic polymer and cationic surfactant, wherein the anionic polymer is selected from the group consisting of carboxymethyl cellulose, carboxymethylated starch, xantham gum, guar gum and polyacrylic acid, the cationic surfactant is selected from the group consisting of alkyltrimethyl amine and alkyl imidazoline and the anionic surfactant is the sodium soap of tall oil fatty acid wherein the ratio, by weight, of charged polymer to oppositely charged surfactant is approximately 1 to 1.
